What are the differences between session storage and local storage in Angular?

Session storage and local storage are both part of the Web Storage API, but they serve different purposes. Session storage is limited to the duration of the page session, meaning data is lost when the tab is closed. Local storage, on the other hand, persists even after the browser is closed, allowing data to be stored indefinitely until explicitly deleted.

Can you give me an example of how to use session storage in an Angular app?

Sure! In Angular, you can use the sessionStorage object to store data. For example, you can set an item like this: sessionStorage.setItem('key', 'value'); and retrieve it using sessionStorage.getItem('key');. This will store the data for the duration of the page session.

Is there a limit to how much data I can store in session storage?

Yes, most browsers limit the amount of data you can store in session storage to about 5-10MB. It's important to check the specific limits for the browser you are targeting.

When should I use local storage instead of session storage?

You should use local storage when you need to persist data across sessions, such as user preferences or settings. Use session storage for temporary data that only needs to last for the duration of a single session.
